Hello everyone,

I have a requirement to input data from a set of daily produced brd files and then create an export of what is inside them.
The problem i have is that sometimes not all of the brd files are produced which is correct and which causes the multiple brd node to fail with a (zero readers passed) error which causes the rest of the graph to fail.

I wondered if there is a way to default the data to spoof an empty default brd file if the data is empty and pass that into the collector or is there a way around this issue with the multiple brd node?

Regards,

Keith

Just keep a dummy.brd file in your data directory that contains a header of the same brd files you read. When the dummy.brd is read using the directory list node you can simply remove that record with a filter node.

If you empty your data directory after the data is read you can keep the dummy.brd in a different directory and copy (use the appendBrd function) it into your data directory using a filter node before you begin processing the data. You will need to pass in 1 record to the filter node thru a static data node to get the filter to execute the appendBrd command.

Hope this helps...

Thanks,
Larry

Hi Keith,

You could use the Meta Check to determine whether the Multiple BRD should run or not? I have provided an example below.

If the graph needs to run through though, you would be best using the method that Larry suggests above.


- - - - - - - - copy all text below this line into your graph - - - - - - - -

node:Check_there_1_record
bretype:core::Meta Check
editor:Label=Check there >=1 record
editor:sortkey=537b5c010dce657a
input:@43c285fc347d19f2/=Directory_List.40fd2c747c2b1c0a
prop:MinimumRecordCount=1
prop:SuccessAction=Clock
prop:TerminusAction=Output
editor:XY=360,70
end:Check_there_1_record

node:Directory_List
bretype:core::Directory List
editor:sortkey=537b5bcb327659c2
output:@40fd2c747c2b1c0a/=
prop:DirectoryName=H:\
prop:Pattern=*.brd
editor:XY=280,140
end:Directory_List

node:Multiple_BRD_Files
bretype:core::Multiple BRD Files
editor:sortkey=537b5bc811fb6298
input:@40fd2c7405e716f4/=Directory_List.40fd2c747c2b1c0a
output:@40fd2c74028104af/=
inclock:/=Check_there_1_record
prop:Filename=<<EOX

EOX
editor:XY=430,140
end:Multiple_BRD_Files
